Due to the lack of available defensive players, Klopp used his creativity to change the positions of other existing players instead of using an academy player. Klopp believes that these players who have been transformed into positions are no worse than starters, just like Mascherano.
Injuries in the defense line forced the German coach to use his adaptability and immediately launched the "Mascherano Plan" to fill the gap in the defense. The only central defender available for the team is Joe Gomez. It seems that the preferred solution may be to use youth players, but Klopp said he can change the positions of other players. "We have other options, like Henderson, Wijnaldum, Milner or Robertson, they can all play that position. Mascherano has done a good job at the guard position, and they are no better. Scherano is bad," Klopp said in an interview.
In the final period of his career, Mascherano changed his position from midfielder to central defender. This change mainly occurred in Barcelona. After Puyol retired, he partnered with Pique as a central defender, and this position change was later brought to the Argentine national team.
